Antwort: (RADIATOR) Re: *GhostSessions Problem

[Hugh Irvine]

Hello Christian -

As I discussed in a previous mail, Radiator can use the NasType 
parameter in the Client clause(s) to enforce strict session limit 
checking with the NAS equipement being used, as long as the NAS can be 
queried successfully.

Unfortunately, we cannot provide solutions for all types of NAS and all 
versions of NAS software, so it becomes a matter of trial and error for 
Radiator users to work out how to make things work in their own 
environment. We have provided a number of NasType modules and the source 
code for all of them is in the "Radius/Nas" directory.

The only thing I can suggest is that you test the query that Radiator 
tries to run by hand to see what result you get, and if it is not 
correct then you will need to verify what is wrong in the code and 
correct it. It may also be the case that you need a different version of 
the SNMP code for example, or that your NAS needs to be configured to 
respond correctly to the query that Radiator tries to send.

Note that we do not have any NAS equipment ourselves and we rely on 
customers to do their own testing. Many customers have done exactly this 
and contributed their code, most of which is what is found in the 
Radiator distribution.

This is a vexing problem, I know, but there is little I can do to help 
you.

regards

Hugh
